It feels as if the sky is alive there in terms of the way it is coloured and all. I think it's fantastic how there is a mixture of darkness and light... and how it is quite fiery, as if it is nearing darkness overall.
The way you have positioned it is cool, and I like the reflection as well. It's great how the land breaks up the sky and water a bit and how the clouds add so much to everything too. I don't think this would be as awesome without the clouds.
